Problems solved by technology

[0002] The processing of existing ring inductors mostly relies on manual and automatic winding machines to process and wind enameled wire coils, but the above-mentioned processing technology is powerless when faced with the processing of ring inductors with a wire diameter above 0.5mm, and cannot break through the size limit. On the other hand, considering the deviation of the finished product of the magnetic material itself due to the processing technology and material, usually about 20%, it is necessary to design a device that can automatically process high-precision ring inductors

Embodiment 1

[0028] Such as Figure 3-4 As shown, a high-precision inductor processing device driven by a magnetic field, first uses special equipment to process a fan-shaped copper wire coil 1, and cooperates with two semi-circular annular shells 2 that can be rotated on the inner circumference. The coil 1 is assembled on the casing 2, and the magnetic strip 4 is wound into the rotatable part of the casing 2 through the window 3, that is, the inner circumferential groove 5, and its structure is similar to a tape measure. By applying an external magnetic field7 (eg figure 1 As shown, the axial section of the semi-circular shell 2 is placed in the magnetic field 9), and is wound by a height-adjustable brush 10. On the good copper wire coil 1, when the inductance reaches the actual required value, the brush 6 is controlled by the program command to stop the power supply, and then the winding process of the inductor is completed.

Embodiment 2

[0032] Such as Figure 5-6 As shown, a mechanically driven high-precision inductor processing device uses a fan-shaped copper wire coil 1 processed by special equipment, and two rotatable shells 2 on the inner periphery of the special purpose, that is, there is a groove 5 on the inner circumference of the shell 2, and the groove There is a ring gear 6 inside the 5, the ring gear 6 meshes with a pair of gears 7, the copper wire coil 1 is assembled on the shell 2, and the magnetic strip 4 is wound on the rotatable part of the shell 2 through the window 3, usually by glue The process fixes the ring gear 6, and then winds it through the gear 7. The number of rotations of the winding is connected to the wound coil 1 by the instrument for testing the inductance. When the inductance reaches the actual required value, the gear is controlled by the program command. 7. Stop the rotation and complete the winding of the inductor.

Abstract

The invention discloses a processing device and method for a high-precision inductor. The method comprises the following steps: 1, winding a copper coil (1); 2, assembling the copper coil well wound in the step 1 with casings (2); 3, winding a magnetic core in the casings (2). Winding of a magnetic strip is controlled through a rotatable part in the casings (2), so that the rotatable part is matched with inductance measurement equipment, connected with the copper coil (1), to measure the inductance value, when the inductance value meets the requirement, the rotatable part is stopped, and production of the inductor is finished. Electrical parameters of the inductor have high consistency, meanwhile, use of an inductor with a large wire diameter is not dependent on manual operation any more, and the production efficiency and the product quality are improved greatly.

Description

technical field [0001] The invention relates to a processing method and device for ring inductors, especially a method and device capable of automatic processing while realizing precise control of inductance. The invention can be used for common mode inductors (double windings), differential mode inductors (single winding ) and ring transformer (multi-winding) processing. Background technique [0002] The processing of existing ring inductors mostly relies on manual and automatic winding machines to process and wind enameled wire coils, but the above-mentioned processing technology is powerless when faced with the processing of ring inductors with a wire diameter above 0.5mm, and cannot break through the size limit. On the other hand, considering the deviation of the finished product due to the processing technology and material of the magnetic material itself, usually about 20%, it is necessary to design a device that can automatically process high-precision ring inductors....
